SHINGLE MACHINE Specification of Letters Patent.

Patented Aug. 27, 1907.

Ap licati n med January 26,1996. Serial No. 298,078.

To all whom it may concern:

Be it known that I, FRANK WA'r'rs BURPEE, a citizen of the Dominion ofCanada, and a resident of the city of Vancouver, in the Province ofBritish Columbia, Canada, have invented certain new and usefulImprovements in Shingle-Machines, of which the following is aspecification.

My invention relates to machines for sawing shingles,

particularly of the type illustrated in my Patent 7 60,610

and the primary object thereof is to improve and simplify suchconstructions.

Other objects will be set forth in the following description and thosefeatures of construction upon which I desire protection, succinctlydefined in the appended claims.

In the accompanying drawings in which like numerals of referenceindicate like parts throughout the several views: Figure 1 is a frontview of a machine constructed inaccordance with my invention with partsremoved. Fig. 2 is a top plan view thereof. Fig. 3 is a detailfragmentary view in perspective of the lower track for the carriage.Fig. i is a detail fragmentary side view of the upper track. Fig. 5 isan end view thereof. Fig. 6 is a view in perspective of the saw frame,and Fig. 7 is a fragmentary detail showing more clearly the adjustableconnection of the saw frame to the base of the track frame.

In the drawings reference numeral 1 indicates the usual verticallydisposed rectangular track frame of an upright shingle sawing machine, 2the carriage thereof and 3 the mangle rack which is connected to thecarriage 2 by a link 3 and operated by a pair of pinionsB as in myaforesaid patent.

The carriage, which can be of any desired construction, has secured toits base truck frames 4 in which are mounted wheels 5, and these wheelsbear on a track 6 arranged on a bed 7 which is supported in the lowerportion of the track frame. Secured to the top of the carriage areguides 8 which slidably embrace a track 9 secured to the upper portionof frame 1.

Both of the tracks 6 and 9 are square in cross section and each has fourtreads, the side faces of track 9 being the treads thereof and thelongitudinal edge portions of track 6 serving in a like capacity.Therefore track 9 has flat treads and track 6, V-shaped treads.

The tracks are preferably clamped between suitable jaws, as 10 and 10.the former being fixed and having the latter, which is removable, boltedthereto as shown. By providing each track with a plurality of treads,the usefulness of the tracks is prolonged, for, when their active treadsbecome worn, the jaws 10 can be removed and the tracks then turned so asto bring new treads into position for service. As now considered, track9 has opposite faces simultaneously serving as active treads, the guides8 being arranged in pairs, and tracks 6 on which the wheels 5 roll, hasbut one of its treads in active use at a time. I

Reference numeral ll. indicates the husk frame which is pivoted at 12,to an offset portion of the bed 7. said offset portion being in the formof a stand 13 and having its free end portion supported by legs '13. Thehusk frame comprises a base part 14. having at its outer end portionlegs 14 which are mounted for sliding movement, as on a plate 15. andsuitable means is provided for adjusting this frame so as to adjust; theload of the saw relatively to the line of travel of the carriage. Thisadjusting means consists of screws l (i, mounted in lugs 17 of the plate15 and having threaded engagement therewith and having their outer endsengaged in recesses in the legs 14, whereby by loosening one screw .1 f3and tightening the other the husk frame can be adjusted on its pivot 12.

ln'order to hold the husk frame more firmly in its adjusted position, Iprovide a lock means therefor. the same consisting of a bolt 18 mountedin a lug 18 of said frame and projecting through a slot 18 in the stand13, and having on its threaded end portion a nut 19 (see Fig. 7), whichcan be readily released or tightened when desired.

Reference numeral 20 indicates spaced apart stands of the husk frame inwhich is journaled an arbor 21. This arbor carries a driving pulley 21and the shingle saw 22 and said driving pulley has one of its endportions, as 21 beveled so to serve as a friction gear which is engagedby a friction gear 23 fixed to one end of a cross shaft 24, journaled ina branch arm 20 of the outer stand 20. Cross shaft 24 is also providedwith a pulley 25 over which a belt 26 passes, said belt also passingover a pulley 27 fixed to an arbor 28, which carries the jointing saw.

In addition to having the power from arbor 21 transmitted to the arborof the jointing saw, I also drive the drive-shaft 29 of the feed worksof the machine therefrom by means of a belt 30 which passes over asuitable pulley thereof and a friction clutch pulley, as 31, which ismounted on the drive shaft 29. The clutch mechanism of this pulley isoperatively connected to a suitably fulcrumed treadle, as 32, throughthe medium of a rotatably mounted rod 33 having laterally extending arms33 and 33", a lever 34 fulcruined at 34/ and pivotally connected to theclutch mechanism and arm position of the saw, Fig. 2), otherwise the sawwould run out of its true line of cut into the wood, but by providing anadjustable husk frame on which the saw is mounted, the saw can beadjusted so as to be given a proper lead which will overcome to a markeddegree, friction of the block on the saw, as that side face of the sawwhich faces the shingle bolt will be out of contact with the shinglebolt during both the advance and return movements of the carriage.

The track 6 and 9 as herein shown, are of the particular form nowemployed by me, it is obvious however that the number of treads on thesetracks can be readily varied at will.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent of the United States of America, is:-

1. In a machine of the type set forth, a frame, a carriage mountedthereon, a saw frame arranged at one side of said first frame and beingpivoted at one end portion for horizontal adjustment, legs on theopposite end portion 01 said saw frame supported for sliding movement,means connected to said legs for adjusting said saw frame, and a saw foroperating on the work as conveyed mounted on said saw frame for movementtherewith.

2. In a machine of the type set forth, a frame, a carriage mountedthereon, a saw frame pivoted at one end portion of said first namedframe, depending means fixed to said saw frame for supporting the freeend portion thereof, means slidably supporting said last named means, asaw for operating 011 the work as conveyed mounted on said saw frame formovement therewith, and means for adjusting said saw frame, for thepurpose specified.

3. In a machine of the type set forth, a frame, a carriage mountedthereon, a saw frame pivoted at one end portion of said first namedframe, legs fixed to said saw frame for supporting the free end portionthereof, means siidahly supporting said legs provided with lugs havingscrew threaded openings, and screws mounted in the openings in said lugsand engaging said legs for effecting adjustment ofsaid saw frame, forthe purpose specified.

4. In a machine of the type set forth, a frame, a stand fixed to saidframe and projecting outwardly therefrom, a carriage mounted on saidframe, a saw frame pivoted at one end portion to said stand, meanssupporting the free end portion of said saw frame for sliding movement,a saw for operating on the work as conveyed mounted on said saw framefor movement therewith, and means to adjust said saw frame to presentthe faces of said saw at an angle to the plane of its cut.

In a machine of the type set forth, a frame, a carriage mounted thereon,a stand fixed to said frame and projecting outwardly therefrom, a sawframe pivoted at one end portion to said stand, legs on the free endportion of said saw frame, means siidahly supporting said legs, meansengaged with said legs for adjusting said saw frame, a saw on said sawframe for operating on the work as conveyed, and means on said saw frameengaged with said stand for securing the saw frame from movement Signedat Vancouver, B. C. this 17th day of January 1906.
